LIGHTING-FIXTURE.

Specification of Letters Patent.

Patented Feb. 20, 1917.

Application filedJune 14, 1916. Serial No. 103,599.

and resident of Milwaukee, inthe county of Milwaukee and State ofWisconsin, have invented new and useful Improvements inLighting-Fixtures, ofwhich the following is a description, referencebeing had to the of this specification.

The invention relates to lighting fixtures and more particularly toelectric light fixtures.

The invention is designed to provide a lighting fixture in which thelighting may be both direct or indirect or either one of these. This isaccomplished by mounting on a suitable support a pair of oppositelydisposed sources of light with a deflector plate disposed therebetween.

A further object of. the invention is to provide an extensible supportfor the lights composed of telescoping sections with spring means forfrictionallv holding said sectlons to permit of their adjustment.

The invention further consists in the several features hereinafter setforth and more defined by claims at the conclusion hereof.

In the drawings:

Figure .1 is a vertical sectional view of the device embodying theinvention; and

Fig. 2 is an enlarged detail view of a part of the device shown in Fig.1 showing the connection between the lamps, the support andthereflectors.

The device comprises a support, a pair of oppositely disposed sources oflight and a reflector interposed between said sources of light carriedby said support.

The support comprises a tubular base section 4 and telescoping tubularsections 5 and 6, the section 5 telescoping withm the base 4 and thesection 6 within the section 5. Means are provided for frictionallyholding these telescoping sections with respect to each other for thepurpose of adjustment and means are also provided for locking saidsections in adjusted position.

The frictional holding means comprises spiral shaped springs 7 and 8secured by pins 9 and 10 to the lower ends of the sections 5 and 6respectively said springs depending below the ends of said sections soas to engage the inner sides of the sections 4 and 5 respectivelywhereby said sections lucid material, such as glass,

may be adjusted with respect to each other I and held by the springs inadjusted position. To fixedly secure the sections in adjusted position Iprovide set screws 11 and 12 passing through threaded apertures 13 and14 in. the upper ends of the sections 4 and 5 respectively to engage thesections 5 and 6 respectively. 4

The upper end of the section 6 is provided with acap or plug 15 in whichupwardly extending spaced apart lamp supporting and conductor carryingtubes 16 are secured. Telescoping within the upper portions of saidtubes 16 are spaced apart lamp supporting and conductor carrying tubes17 which are adapted to be secured in adjusted position with respect tothe tubes 16 by set screws 18. The ends 19 of said tubes are threaded toengage in oppositely disposed threaded bores 20 in a hollow fitting 21.Secured to the fitting 21 are the lights and reflector. previouslyreferred to.

The interior of the upper end 22 of the fitting 21 is threaded toreceive the threaded end 23 of the socket for the electric lamp 24 andthe interior of the lower end 25 of the fitting 21 is threaded toreceive the threaded end 26 of the socket for the electric lamp 27.

The fitting 21' is provided with a shouldered portion 28 and, a tubularportion 29 threaded at its upper end for receiving a threadedlockingcollar 30 forsecuring the reflectors for the lamps 24 and 27 and thereflector to the fitting 21.

The lamp-24= is provided with an upwardly projecting hemisphericalreflector 31 of translucid material, such as glass, and having a centralaperture 32 through which the portion 29 of the fitting 21 passes andthe lamp 27 is provided with a downwardly projectmg hemisphericalreflector 33 of transand having a central aperture 34 through which theportion 29 of the, fitting 21 passes. The lamps 24 and 27 are oftranslucid glass to allow a portion of the light to pass through themand at the same time reflect another portion of the light.

The .reflector consists of a circular opaque disk 35 provided withreflecting surfaces 36 and 37 and with a central aperture 38 throughwhich the portion 29 of the fitting 21 passes.

Interposed between the shouldered portion 28' 0f the fittin and '19.Ynfltmfnv 22 ia n cushion 39 preferably a ring of soft felt and similarcushions 40, 4:1 and 42 are interposed between the reflectors 33 and 35,re-

flectors 35 and 31 and reflector 31 and collar 30 respectively. Thus thereflectors 31, 35 and 33 are all mounted on-the fitting 21 and securedthereon between the shouldered por tion 28 of said fitting and thecollar 30.

Each lamp 24 and 27 is provided with any suitable form of socket switchwhich is operated by a pull cord 43, the pull cord for the lamp 24;passing down through apertures 44:, 45 and 46 inthe reflectors 31, 35and 33 respectively. Thus both of the lamps: may beused or either one ofthem as desired.

Conductor wires 47 and l8-connected with any suitable source of supplypass upwardly through the tubular supporting sections 4., 5 and 6, theconductor wires t7 passing through one pair of telescoping tubes 16 and17 into the fitting 21 and thence to the lamp 27 and the conductor wires48 passing through the other pair of telescoping tubes 16 and '17 intothe fitting 21 and thence to thelight 24. It will he noted that thetubes 16 and 17 extend from the support 'to a position wellwithin thereflector 33 so that reflectors of varioussizes maybe used withoutinterfering with the support.

The light from the lamp 24 passes upwardly and at the same time some ofit passes downwardly through the reflector 31 and strikes the reflectingsurface 36 of the disk 35 and is reflected upwardly. The light from thelamp 27 passes downwardly and at the same time some of it passesupwardly through the reflector 33 and strikes the reflecting surface 37of the disk 35 and is refie'ct eddownwardly. V V a While I have shownthe device as provided with a base member more suitable for use as afloor lamp, it will be understood that the device may be inverted andsuitably suspended from the ceiling.

The invention thus exemplifies a lighting fixture adapted for direct andindirect lighting and one in which the reflectors are simply andcompactly mounted upon a fitting for the lamps.

What 1 claim as my invention is:

1. A lighting fixture comprising a support, a fitting mounted thereon,vertically disposed lamps secured at the opposite ends ofsaid fitting, atranslucid reflector for each lamp, a metallic reflector disposedbetween said translucid reflectors, and means for detachably securingsaid reflectors upon said fitting.

2. A lighting fixture comprising apair of oppositely disposed lamps,translucid reflectors for each of said lamps, an opaque reflectordisposed between said translucid reflectors, and supporting meansincluding tubular telescoping sections, and springs-secured to the endsof the inner telescoping sections and bearing upon the inner sidesof theouter telescoping sections to hold said sections in adjusted. position.

3. A lighting fixture comprising an extensible support, a fittingmounted thereon, vertically disposed electric lamps secured at theopposite ends ofsaid fitting, translucid glass-reflectors for each lampmounted on said fitting, and an opaque disk having upper and lowerreflectingsurfaces mounted on said fittin between said glass reflectors.

4. A lighting fixtureincluding a fitting having an outer shoulderedportion and a threaded end, vertically disposed lamps secured at theopposite ends of said fitting, glass reflectors for each of said lampshaving centrally disposed apertures through which said fitting passes, ametal reflector having a centrally disposed aperture through which saidfitting passes, said reflectors being mounted on said fitting betweensaid shoulde'red portion and said threaded end, cushioning meansinterposed between said reflectors and fitting, and a collar fittingonto the threaded end of the fitting for securing said reflectors andcushioning means between it and said shouldered portion.

In testimon whereof, I aflix my signature.
